Always fault find by doing the easiest thing first.
1. Jumpstart from the car. Making sure you dont crank over too long as you dont want to cook the starter.
2. Check the fuel filter ( disconnect the carby end ancheck for fuel flow out, redirect fuel into a catch bowl of some sort, dont want to burn the bike)
3. Check air filter, while there try a little petrol or aero start in the carbs ( couple of drops should do) and crank again. Bike should fire up, and should rum for a moment or two. Put cover back on (prime again first) try starting again.
4. If it runs, let it keep going to warm up. If not, connect battery charger, put tools away and jumper leads. Go inside, swear at bike, grab a beer sit and watch TV. try againt to start tomorrow.
5. Come out fresh with positive attitude, start bike first go and go for a ride, burn a tank of fuel. Return home happy and refuel.
